Synchronization of Photovoltaic Systems in Single-Phase Grid-Connected Under Grid Faults
The highly increasing penetration of single-phase photovoltaic (PV) systems pushes the grid requirements related to the integration of PV power systems to be updated. These upcoming regulations are expected to direct the grid-connected renewable generators to support the grid operation and stability both under grid faulty conditions and under normal operations. Grid synchronization techniques play an important role in the control of single-phase systems in order to fulfill these demands. Thus, it is necessary to evaluate the behaviors of grid synchronization methods in single phase systems under grid faults. The focus of this paper is put on the benchmarking of synchronization techniques, mainly about phase locked loop (PLL) based methods, in single-phase PV power systems operating under grid faults. Some faulty mode cases are studied at the end of this paper in order to compare these methods. It is concluded that the Enhanced PLL (EPLL) and the Second Order Generalized Integrator based PLL (SOGI-OSG PLL) technique are the most promising candidates for future single-phase PV systems due to their fast adaptive-filtering characteristics.

Fea for WEDM Process of Titanium Alloy
Advance non-conventional machining processes are use in modern manufacturing system. In Titanium alloy specimen condition machining process are require maximum energy. Wire electrical discharge machining (WEDM) is widely used in machining of conductive materials when precision is considered as a prime importance. This work proposes a three dimensional finite element model (using ANSYS software) and new approach to predict the temperature distribution at different pulse time as well as stress distribution in non-conventional machining for Titanium Alloy Specimen. A transient thermal analysis assuming a Gaussian distribution heat source with temperature-dependent material properties has been used to investigate the temperature distribution and stress distribution. Thermal stress developed after the end of the spark and residual stress developed after subsequent cooling. The effect on significant machining parameter pulse-on-time has been investigated and found that the peak temperature sharply increases with the parameter.

Experimental Study on Self Compacting Concrete Having Grade M70
Self compacting concrete (SCC) is a new category of high performance concrete which flows under its own weight. It does not require any external vibration and compaction. The work focused on concrete mixes having water/cement ratios of 0.25, with a packing factor of 1.12. The Concrete mixes contains constant proportions of Super plasticizers, and constant proportions of Cement, Micro Silica, VMA, Coarse aggregate and Fine aggregate for a constant water cement ratios. The percentage of Micro Silica added is 7% for all mixes. The mix proportions are obtained on the basis of NAN-SU mix design. The mixes contain Cement of 574 kg/m3 for 0% addition of fly ash, it vary for 5%, 10% &15% addition but with same total binder content. The workability tests performed in this research were as per EFNARC specifications. Based upon the experimental results, for a water cement ratio of 0.25, fresh and hardened state properties of high strength self-compacting concrete are evaluated. Due to so many advantages of this concrete, it is suitable for the situations where congested reinforcement is used. In this paper presents self compacting concrete is developed using various percentages of fly ash 0%, 5%, 10%, 15% by weight of cement as partial replacement of cement and the strength of concrete has been assessed.

Malaria Cells Detection Using Digital Image Processing Methods
In recent years the image processing mechanisms are used widely in several medical areas for improving earlier detection and treatment stages, in which the time factor is essential to find the sickness in the patient as conceivable as quick, particularly in different ailments, for example, the Malaria fever. Jungle Fever has been drawing in the consideration of restorative and sciatic groups in the most recent years due to its high commonness aligned with the troublesome treatment. Insights from 2008 demonstrate that Malaria sickness fever, all through world, is the one that assaults the best number of individuals. Early discovery of Malaria is imperative for fruitful treatment. There are couple of strategies accessible to identify Malaria cells. Here two strategies for division, for example, thresholding and watershed are utilized to distinguish the jungle fever cell. Image quality and precision is the center variables of this exploration, image quality appraisal and additionally change are relying upon the upgrade arrange where low pre-handling strategies is utilized in view of Depth-Buffer Method. Following the division standards, an improved district of the question of intrigue that is utilized as an essential establishment of highlight extraction is acquired.

OFDM Based Key Generation Technique
With enhancement in wireless technology, security has become an important part in designing of network. Network security is an important aspect of system administration. We are living in a world where there is access to information anywhere, anytime, be it voice, multimedia or data analytics. This information should be provided to the user with the highest possible security. Thus the information exchanged for communication should be highly secured, authentic and only accessible to the authorised user. Recent research has shown that, this security can be provided through RSS (Received Signal Strength) based key generation techniques for authentication of user. But RSS based key generation technique has a drawback that the key generation rate is very low. Also RSS based technique is highly applicable for mobile devices. In M2M Communication the devices can be static or mobile based. So we explore a technic which is based on Key generation through CSI (Channel State Information) of a channel. Key generation using CSI information can be efficient in the terms of providing security as they can generate quiet a long key as compared to RSS based technique. We deploy an algorithm as a solution to key generation without using additional hardware for key generation and verify that the malicious user is not able to decode the key sighting to the randomness obtained to our algorithm. The major portion of the algorithm concentrates on making the key random so that the attacker is not able to decode the key within a time span which is vulnerable to the communication. When an attacker tries to use the same algorithm and try to sabotage the communication, due to the property of CSI information of OFDM channel, the generated key will be different. Thus it will not match with the secret key used for actual communication. Hence the user will not be able to hijack the communication.

Riverfront Development of Gomati River in Sultanpur City
Sultanpur is distinguished for its unique culture. Sultanpur, and other name kushbhawanpur. Goddess Durga at the beginning of navratra and leaves on vijyadashmi but in sultanpur district, Durga enjoy an extended stay it is the most well-recognized festivals of Sultanpur. About 130 KM from the state capital, this town turn into a ‘mini Kolkata’ during this period with hundred of Durga idols in a vast temple complex. The river area is a heart of Sultanpur. Sultanpur is a headquarters of the Sultanpur district, north side of this district is bounded by faizabad district, south side is bounded by pratapgarh district, the west side is bounded by Barabanki district & Raibareli district. And the east side bounded by Azamgarh district, Ambedkarnagar district, and jaunpur district. Gomati river is which drains almost the whole city and district. Sultanpur has a dry climate with 20 to 28 degree Celsius. This is wonderful Zone of riverfront. These cities no polluted and cleanness. Sultanpur are ecological and natural resources.
